How to Fix a Leaking Hydraulic Cylinder

A leaking hydraulic cylinder repair needs immediate attention, you risk permanently destroying a hydraulic cylinder by running it beyond its design life. The amount of hydraulic fluid that is in your hydraulic system will determine how long the hydraulic cylinder has before it has to be replaced, and the longer you leave a hydraulic cylinder out of your maintenance regime the greater the chance that it will need replacement. To ensure minimum downtime for a hydraulic cylinder, it is critical to ensure that your hydraulic systems are serviced as scheduled, and that your hydraulic system’s hydraulic valves are regularly serviced by professionals. In the event that there is a loss of hydraulic fluid the system’s hydraulic cylinder will self-destruct within 24 hours. If this occurs then it is imperative that the system is immediately replaced, and all adjacent hydraulic components are serviced simultaneously.

Hydraulic Cylinder Leaks

All hydraulic cylinders are not the same size, so one repair procedure may not be suitable for all hydraulic systems, so it is critical that you follow any specific instructions that come with your hydraulic system to the letter when performing repairs to your hydraulic cylinder. Because these hydraulic cylinders contain high concentrations of hydraulic oils they are susceptible to damage from extreme temperatures; so it is important to avoid exposing them to extreme heat while undergoing repairs. It is also extremely important that you protect all seals to prevent leaks whilst repairs are being carried out, and never seal a hydraulic cylinder while under repair.

In most cases of leaking hydraulic cylinder damage, the cause is a result of mineral build-up inside the hydraulic cylinder. As time passes, small pieces of minerals will begin to leak out into the hydraulic fluid and this will gradually lead to complete and total failure of the hydraulic cylinder. It is very important that you protect your hydraulic cylinders from this mineral build-up and that you never allow any minerals to leak into your hydraulic system. If a piece of debris or a small piece of dirt is stuck in the hydraulic lines and it becomes lodged inside a tight spot, then the only way to remove it safely is to flush it out with some water. You should never clean a hydraulic cylinder with a jet of water, as this could lead to the loss of the fluid or the freezing of the hydraulic cylinder lining. To avoid any problems, make sure that you always follow the manufacturer’s instructions when performing repairs and final maintenance procedures on your hydraulic cylinders and lines.
